AUTO-BUMPER.

Application filed August 23, 1920.

To all whom it may concern.

Be it known that I, LOUIS COHEN, a citizen of the United States,residing at J ohnstown, in the county of Fulton and State of New York,have invented a new and useful Auto- Bumper, of which the following is aspecification.

This invention relates to bumpers, and more particularly to bumpersdesigned for use in connection with motor vehicles, it being the primaryobject of the invention to provide movable end sections, movable in onedirection, to eliminate any possibility of the ends of the bumper beingdamaged" by meeting with obstructions when the motor vehicle suppliedwith the bumper is being backed.

A further object of the invention is the provision of resilient meansfor returning the movable end sections of the bumper to their normalpositions after the same have encountered anobstruction.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimed, without de arting from the spirit of theinvention.

eferring to the drawing Figure 1 illustrates a plan view, partly brokenaway, to illustrate the interior. construction of thebumper.

Fig. 2 illustrates a sectional view taken on line 2-2 of Fig. 1.

Fig. 3 illustrates a sectional view taken online 3-3 of Fig. 1.

Referring to thedrawing in detail, the.

reference character 5 designates the main or body portion of the bumper,which is formed preferably of channel iron, the ends thereofbeing'formed at angles as at 6 to provide abutments for the innerextremities of the movable end sections 7.

Each of these movable end sections 7 is secured to the body portion 5 asby means of the hinged connections 8, which connections permit the endsections 7 to hinge forwardly, but prevent the end sections from movingrearwardly beyond a predetermined point, the inner ends of the sections7 abutting with the outer ends of the body portion 5, to lend rigidityto the end sections to per Specification of Letters Patent.

part of the 'bythe reference character 9, there being provided asecuring bolt 10 passing through the tubular member 9 and having one endthereof secured to the front wall of the body portion 5 in a manner toretain the tubular member 9 against movement with relation to the bodyportion 5.

The ends of the tubular member 9 are braced against movement by *meansof the plates 11, which are disposed at opposite ends of the bodyportion 9, there being provided bolts 12 for securing the plates 11 tothe body portion, the ends of the -tubular member 9 being howeverdisposed in spaced relation with the ends of the body portion 5.

Extending rearwardly from the body portion 5 at points adjacent to therespective ends thereof, are a pair of arms 13 disposed in spacedrelation with each other, the arms being connected however by means ofpivot pins 14, which pivot pins provide supports for the pivoted arms15, the inner extremities 16 thereof being designed to contact with theplunger heads 17 of the plungers 18, which are shown as operating in theends of the tubular member 9. a

Spring members 19 are disposed on the plungers 18 and have their innerextremities contacting with the securing bolt 10, the outer ends thereofcontacting with the heads 17 to normally urge the plungers to the limitsof their outer movements, with the result that the outer extremities ofthe arms 15 are placed under the tension of the springs 19 to move theends 7 to their normal positions.

A pair of arms indicated at .20 are carried by each of the end sections7, which arms are connected by the shafts 21 which in turn support therollers 22 that operate over the curved surfaces 23 of the free ends 24of the arms 15, so that movements of the end sections 7 toward theforward portions of the bumper, cause the rollers 22 to gnove over thecurved surfaces 23 to place the coiled springs 19 under tension, so thatwhen the end sections 7 are released, the coiled springs will urge theplungers outwardly to move the end sections rearwardly to positions asindicated by Fig. 1 of the drawing.

In the operation of the device, assuming menses that a motor vehiclesupplied with a bumper constructed in accordance with the presentinvention, is being backed from a garage, and the front wheels of thevehicle have been turned to cause the bumper to contact with the sidemembers of the door frame, it is obvious that the end sections 7 willmove outwardly, thereby relieving the bumper of the strain caused by thebumper meeting with the obstruction.

Having thus described the invention, what is claimed as new is 1. Abumper including a central body portion and movable end sections, atubular member supported within the body portion, plungers operating inthe tubular member, pivoted arms carried by the body portion and havingone of their respective ends contacting with the plungers, and meanscarried by the movable end sections and contacting with the pivoted armsfor moving the plungers in one direction.

2. A bumper including a central body portion and movable end sections, atubular member carried by the body portion, plungers moving in thetubular member, resilient means for normally urging the plungersoutwardly, and means pivotally supported adjacent to the ends of thebody portion and contacting with the plungers and movable end sectionsfor forcing the movable end sections to their normal positions.

3. A bumper including a central body portion and movable end sections, atubular member supported by the body portion, a'plunger operating ineach end of the tubular member, a pair of arms disposed adjacent to eachend of the body portion, a pivoted arm carried by the first mentionedarms, the inner extremities of the pivoted arms contacting with theplungers, each of the pivoted arms having a curved surface, and meanscarried by each end section and contacting with the curved surfaces formoving the plungers Within the tubular member. v

at. A bumper including a central body portion and movable end sections,a tubular member carried by the body portion, and having its endsdisposed in spaced relation with the body portion, a plunger operatingin each end of the tubular member, pivoted means operating at each endof the body portion and contacting with the plungers and end sections,whereby movement of the plungers produces a relative movement of the endsections.

5. A bumper including a central body portion and movable end sections, atubular member supported within the body portion, pivoted arms carriedby the body portion, each or said pivoted arms having connection withthe end sections, and means movable within the plunger and contactingwith the pivoted arms for normally moving the pivoted arms in onedirection.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
